Plasma and High Voltage Electricity
Plasma is very useful for electromagnetic experiments as it will easily react with fields and can alter phase of electromagnetic waves passing through it. The DIY Tesla Coil shown in the projects section was used to generate many of the images shown here.
Below is a collection of photos we've taken of various experiments involving plasma or high voltage and corona. The pictures are displayed via Flickr, for a larger view, click the image to open a new window.

Plasma Dyed Red
Just a picture of some Plasma squiggly stuff that has been altered to look red.
Kirlian Photo of paper smeared with a small amount of a eutectic alloy liquid metal.
The high voltage is provided by a small Tesla Coil and is therfore at a much higher voltage and frequency than a standard HV PSU.
Kirlian Photo of paper smeared with a small amount of a eutectic alloy liquid metal The high voltage is provided by a small Tesla Coil operating with a very high frequency spark gap rate, and therefore lower voltage. This one looks quite different to the version using higer voltages ("Electric Veins")

Magnetic Deflection of Plasma
The central circle is a large circular magnet placed under the special vacuum chamber. Two smaller magnets are above and below it in the image.
The high voltage AC electric field supplied by a power pulse generator is horizontal accross the image, while the magnetic field is coming out perpendicular to your screen.
Single Shot Pulse Discharge
This shows a special device used to contain liquids so that there is effectivley two 'liquid electrodes'
A high voltage capacitor in a power pulse generator is discharged between the areas of liquid. You can see how the plasma spreads across the surface of the larger area of surrounding liquid.
Flame enhanced Arcs (IR Filtered)
Arcs from a small Flame on a Tesla Coil Viewed through a light infrared band pass filter
Arcs from the tip of a Laser Pointer
Arcs from a tesla coil with a small laser pointer lens fixed to the top.
This is NOT a plasma globe. These arcs are in open air.

You are seeing Plasma Filaments emited from a metal sphere of approximatley 5cm diameter.
